Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
- Gamma Flip: Where total GEX changes from negative to positive
Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).
Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).

Understanding ADP gamma exposure
ADP provides options exposure to ADP, which operates in human resource and employment services. Earnings and shifts in orders, production, capital spending, and end-market demand can change option pricing and open interest. The GEX chart shows how modeled exposure is distributed for the contracts and expirations you include.
The ADP call wall, put wall, and gamma flip depend on the contracts included in the calculation. Recompute the chart after changing expirations and compare the distribution around the current price. The output is positioning context rather than a forecast.

ADP GEX methodology and limitations
QuantWheel calculates ADP GEX from the selected expirations, available options data and the formula displayed in the calculator. The result summarizes modeled gamma exposure by strike.
GEX is a model output, not observed dealer inventory or a price forecast. Open interest does not identify who owns an option, and the displayed call wall, put wall and gamma flip can change when the inputs or selected expirations change.
ADP GEX FAQ
What is ADP GEX?
ADP GEX estimates gamma exposure across listed ADP options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. ADP GEX does not reveal actual dealer positions or predict where ADP will trade.
How do I read the ADP call wall and put wall?
QuantWheel labels the ADP call wall as the strike with the largest positive modeled GEX and the ADP put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the ADP price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the ADP gamma flip?
The ADP gamma flip is the price where modeled net gamma crosses zero for the selected ADP options data. Compare it with the current price and the shape of the strike chart. The ADP gamma flip is a model output, not a trading signal.
Which expirations should I use for ADP GEX?
Start with the nearest ADP expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which ADP contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the ADP GEX calculator free?
Yes. You can run up to three free ADP GEX calculations per day on the public tool. After using those calculations, continue for free in the GEX demo. Check the current QuantWheel pricing page for plan access details.
